Infants exposed to domestic violence have poorer cognitive development

A recent study by University of Missouri-Columbia professor Linda Bullock found that infants of mothers with only one abusive partner had worse cognitive outcomes compared to those with multiple male partners, including some who were abusive. This suggests that the absence of support from a father figure can hinder a child's development.

Gut bacteria might be an indicator of colon cancer risk

A recent study published in Cell Host & Microbe found that certain gut bacteria are associated with an increased risk of colon cancer. Researchers discovered a correlation between the presence of non-enterotoxigenic Bacteroides fragilis and inflammation in small polyps. The study suggests that normally healthy gut bacteria may adapt to...

First-of-its-kind study: Use of computer-assisted colonoscopies reduces rate of missed lesions

A new study published in Clinical Gastroenterology and Hepatology found that computer-aided detection can improve colonoscopy quality by reducing the miss rate, with a relative reduction of nearly a third when used in conjunction with standard-of-care colonoscopy. The study suggests that artificial intelligence may be an important tool...

Fiber tracking method delivers important new insights into turbulence

A new experimental method tracks the motion of fibers instead of particles to reveal previously hidden information about turbulent flows. The researchers developed an innovative solution using rigid fibers, which allowed them to measure the speed and direction of flow at two points a fixed distance apart.

How scents take on meaning

A study published by Ruhr-University Bochum's Department of Neurophysiology found that the olfactory system works closely with the brain's reward and aversion systems to form and retrieve memories. Non-olfactory brain regions, such as the limbic cortex, play a crucial role in categorizing scents as pleasant or unpleasant.
